I cvsuped again to get des's recent changes and built world. After a fresh
install, when trying to ssh in i get:
Feb 3 05:02:36 metropolis sshd[3695]: in openpam_load_module(): no pam_krb5.so found
Feb 3 05:02:36 metropolis sshd[3695]: fatal: PAM: initialisation failed
It seems that {build,install}world forgot about pam_krb5.
[daver@metropolis:~]$ ll /usr/lib/pam_krb5*
ls: /usr/lib/pam_krb5*: No such file or directory
[daver@metropolis:~]$ cd /usr/src/lib/libpam/modules/pam_krb5/
[daver@metropolis:/usr/src/lib/libpam/modules/pam_krb5]$ sudo make clean obj all install
...
[snip]
...
[daver@metropolis:/usr/src/lib/libpam/modules/pam_krb5]$ ll /usr/lib/pam_krb5*
lrwxr-xr-x 1 root wheel 13 Feb 3 05:05 /usr/lib/pam_krb5.so@ -> pam_krb5.so.2
-r--r--r-- 1 root wheel 19432 Feb 3 05:05 /usr/lib/pam_krb5.so.2
Then we try to ssh into the machine and,
Feb 3 05:08:14 metropolis sshd[3750]: in openpam_load_module(): no pam_krb5.so found
Feb 3 05:08:14 metropolis sshd[3750]: fatal: PAM: initialisation failed
[daver@metropolis:~]$ ident /usr/lib/pam_krb5.so|grep pam_krb5
/usr/lib/pam_krb5.so:

As a workaround, i can disable krb5 by commenting out the two lines in
/etc/pam.d/sshd which contain pam_krb5.so. Then ssh works just fine.
